deuter Streamer Tube & Helix Valve transparent

The new mouthpiece is leak-free thanks to its water-stop locking action. Simply turn to open. Light pressure activates the drink opening, which provides a pleasingly high flow of liquid regardless of the position in the mouth. When done drinking, the integral spring valve automatically closes the mouthpiece. The “Hi-Flow Bite Valve” is easily disassembled for cleaning.

The attachable protective cap keeps the mouthpiece free from dirt during longer journeys.

The whole system is BPA-free as well as PFC-free.

Helix Valve
The new mouthpiece is drip-proof and has a water stop tap. The tap is opened by a simple quarter turn. With light pressure, the water flow is activated and flows at a comfortable rate. The integrated spring valve causes the mouthpiece to shut automatically. The “Helix Valve” is easy to take apart and clean.
